Can you love someone and cheat on them?

i know some ppl say it is not cheating if u are just kissin and holding hand but i think it is becasue u catch an emotion for someone and yes i also believe u can be in love with some one and still be able to cheat and not have it bug u because u are look for 100 percent in a relationship and u never find it u usually get just 80% so ppl cheat looking for the other 20
